loadTemplateFile()
Description
Loads a template file. If caching is on, then it checks whether a "prepared" template exists. If it does, it gets loaded instead of the original, if it does not, then the original gets loaded and prepared and then the prepared version is saved. addBlockfile() and replaceBlockfile() implement quite the same logic.
Parameter
- string $filename
filename
- boolean $removeUnknownVariables
remove unknown/unused variables?
- boolean $removeEmptyBlocks
remove empty blocks?
